Arran - the mythical island

I thought I would be able to see Arran every day when I look out of my window, but it's becoming a bit of a mythical island. Not quite as bad as Brigadoon, but it certainly doesn't seem to appear often at the moment. I think there's only been one morning so far when it's been visible - it mostly seems to appear for a short while some rare evenings, then usually vanishes again within an hour or so.....

I managed to catch a rare view as Holy Isle started to appear one evening...

And an even rarer view of the sleeping warrior.
